Soulution- a homogeneous mixture where all components are in a single phase. -Gases(ex.atmosphere=CO2, N2, O2) -Liquids(ex.saltwater) Aquesous----> dissolved in water -Soloids(ex.14 karot gold, brass) ----> Alloy
Particle Size <1nanometer they will not seperate on their own (1nm=1x10^ -9m)
Suspension Colloids -larger particle size -medium particle size -great then 1,000 nanometers -will not seperate on their own -will seperate - Tyndall effect *scatters light*
PARTS OF SOLUTIONS Solute--->is the part of the solution being dissolved (changes phase) Solvent---> the part of the solution that is doing the dissolving (retains phase) ex. H2O--Aqueaos Solution Alcohol--Tincture Mercury--Amalgom MOLARITY M = # of moles of solute / L of a solution
MOLALITY m = # of moles of solute / # of Kg of solvent
SOLUBILITY EQUATIONS - this shows what happens when ionic compounds dissolve in water. Ex. NaCL(s) ----> Na(aq) + CL(aq)
Solubility- the maximum amount of th solute that can be dissolved in a given quantitiy of a solvent
Saturated Solution- soultion where the maximum amount of solute has been dissolved
Unsaturated Solution- solution that is not holding it's maximum amount of solute
Supersaturated Solution- a solution holding more solute then is possible
FACTORS AFFECTING SOLUBILITY OF A GAS IN A LIQUID 1) Pressure--> increase pressure, keeps gases dissolved(Henery's Law) 2) Temperature--> increase temperature, makes gases less soluble
SOLUTION MIXING
- this is used when trying to make a diluted solution
- Molarity1 X Volume1 = Molarity2 x Volume2**
